We are having few data nodes in an inconsistent state. frequently goes
dead state. Because of DataXceiver Error
In console we seen the Error.
*INFO hdfs.DFSClient: Could not obtain block*
blk_XXXXXXXXXXXXXXXXXXXXXX_YYYYYYYY from any node: java.io.IOException:
currently we have this value.
dfs.datanode.max.xcievers, dfs.datanode.max.transfer.threads = 4096
currently monitering our cluster JVM monitoring using openNMS,
Not at all hit 4096 value this value for this week . But frequently
the particular node goes dead state why? log says DataXceiver Error.
dfs.datanode.max.xcievers value set to the particular node or across the
cluster Please guide me.
Did I learn something today? If not, I wasted it.
