ColumnFamilyStore: Mbean API support the hex format param (#69)
Cassandra 3.0 version of the JMX added a parameter that allows accepting the parameter as hex. This breaks the current implementation with a NoSuchMethodException. This patch adds the missing implementation. For a full support, a follow up patch in Scylla is needed, but for the current functionality it would work. After this patch usage example: nodetool getsstables keyspace1 standard1 39303138374b4d343830 Signed-off-by: Amnon Heiman <amnon@scylladb.com>
