27313ee2c4 ColumnFamilyStore: Add an implementation for table sampling
This patch adds the implementation for begin and finish local sampling
of a column family.

There is a difference in the implementation of Cassandra API and Scylla.

In Cassandra and the JMX an external source start and stop the sampling.

In Scylla, a single API call start the sampling and return with the
result. In Scylla the API call always return sampling of the read and of
the writes.

To bridge the difference, the begin sampling command will use a Future
when calling the API. The finish method will wait for the future to end.

Because of the different implementation, it is possible that two
consecutive calls will be made to start sampling one for the read and
one for the write, similarly, two calls will be made to finish for read
and write.

The implementation would ignore the second call to start and will
store the result, so the second call to finish will be served from the
stored result.

Note, that the use of future is only for safety, the way we expect it to
work, the caller to the begin sampling will sleep anyhow while waiting
for the result.

To avoid breaking the MBean compatibility we piggyback the duration on
top of the sampler string.

If no duration is given, a default duration will be taken, this is also
just as a precaution, we will modify the nodetool implementation to
pass that information.

There is a known issue with cardinality, that will need to be addressed.
Also we return a value in the raw column to match what Cassandra JMX
returns, but it's a duplication of the partition key.

See scylladb/scylla#2811

ca3fa8de20 scylla-jmx: Fix tablemetricsobjectname breakage
Fixes #57

The usage of TableMetricsObjectName-yada-yada relies on translating the
"fake" objectname to a canonical one on remote
publication/serialization. However, the implementation of
ObjectName.getInstance has changed in JDK (micro) updates so it no
longer applies overridable methods -> wrong name published.

Fix by doing explicit ObjectName instansiation.

9c3ac3e547 scylla-jmx: Update JMX interfaces to origin 3.11
Almost 100% null implementations, which is ok for most purposes
currently used by scylla. Some of these new calls (like dropped
mutations etc) should perhaps however be implemented.

Tested with the nodetool dtests. So sparsely.

Needed when/if scylla-tools-java is upgraded to origin 3.11,
otherwise noodtool breaks.

1ad2ba8507 TableRepository: wrap initial repository
Before we were discarding the initial repository while
overriding it with TableRepository. This was a mistake that
caused dtests to fail. Proper solution is to keep the initial
repository inside TableRepository. That way whatever was registered
at the time of JmxMBeanServer creation is still handled properly.

862aea4a33 Use more efficient MBeans repository
Default implementation stores MBeans in the following map:

<domain name> -> (<properties as a single string> -> NamedObject)

This is problematic because NamedObject contains ObjectName that
has both domain and properties inside itself.

This means we're storing the same data twice.

For domain "" we want to store MBeans in a more compact way using map:

ObjectName -> DynamicMBean

which is equivalent to NamedObject.

455f5717ea Introduce and use TableMetricObjectName
This is a new extention of ObjectName that uses less memory.

TableMetricNameFactory and AllTableMetricNameFactory can
create it instead of regular ObjectName to save memory.

It is possible to save memory because each name created by
TableMetricNameFactory (or AllTableMetricNameFactory) shares
most of its data with other names created by the same factory
and there's no need to create multiple copies.

48408dc6a3 Ensure regular ObjectName is returned to remote callers
Next patch will introduce new ObjectName implementation that
will use less memory. This new object won't be serializable.
This means it won't be possible to transport it to a remote
caller. We want to keep this new object local to JMX server as well.

This patch makes sure that every ObjectName returned
from APIBeanServer is transformed into a regular ObjectName.

It also makes sure that every ObjectInstance returned from
APIBeanServer has its ObjectName swapped with a regular ObjectName.

2c48bab91a Use JmxMBeanServer instead of MBeanServer
JmxMBeanServer is a concrete implementation of a MBeanServer.
We want to use it directly because we need to bypass calls to
JmxMBeanServer.registerMBean and JmxMBeanServer.unregisterMBean.
They take ObjectName as parameter, copy it using
ObjectName.getInstance(ObjectName) and pass it to registerMBean
and unregisterMBean of JmxMBeanServer.getMBeanServerInterceptor().
We want to avoid this copy and pass the ObjectName argument directly
to JmxMBeanServer.getMBeanServerInterceptor().

To do that this patch:
1. changes all MBeanServer variables to JmxMBeanServer
2. creates JmxMBeanServer in APIBuilder making sure accessing
   interceptors is allowed
3. makes sure that JmxMBeanServer.getMBeanServerInterceptor().registerMBean
   is called wherever JmxMBeanServer.registerMBean was called
4. makes sure that JmxMBeanServer.getMBeanServerInterceptor().unregisterMBean
   is called whenever JmxMBeanServer.unregisterMBean was called

Next patch will use different ObjectName implementation that will
use less memory and this patch is crucial because without it every ObjectName
is transformed with ObjectName.getInstance which turns the object into
a regular ObjectName.

4e4589ba6f FailureDetector: check that states is not null before use
When a node is part of a cluster but is down (like in the situation where
a cluster is taken down and up again but not all nodes are up). There is
no application_state information for that node.

This patch check that the information exists before using it to prevent
null pointer exception.

After this patch, a call to nodetool gossipinfo would return the
available information without failing.

ac8743269c scylla-jmx: Allow ssl, auth etc options for JMX connector
Actually removes a bunch of code to manage the JMX connector,
since as of jdk8u102, the standard jmx connector answers to
property setting bind address -> can restrict access.
Note that the RMI connector will now (as is jdk normal)
_bind_ to 0.0.0.0, but it will not answer non-local requests
if "remote" is not enabled. This is the default jdk behaviour.

In any case, we rely on setting the appropriate properties
instead, and also allow pass-through of -D flags to java,
which in turn means those who wish can turn on both auth
and ssl, set key/trust stores etc etc.
