While monitoring JMX attributes via JConsole I observed that there are some
VM arguments being reported multiple times, see example below.
VM arguments: -Xmx32768m -ea -XX:+UseConcMarkSweepGC
-XX:+CMSIncrementalMode -ea -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode
-ea -XX:+UseConcMarkSweep

I am trying to run a M/R job remotely on a HBAse table.
I have added the conf.set("fs.default.name","hdfs://10.0.0.3:6") to the

I just realized that using the increment function creates another version,
with a new timestamp.
Is there a way we can use the previous TS, hence over writing the value ?
