Thanks for the response Dima,
Please find below some of the details: Hadoop Distribution: Hortonworks Version: HBase 1.1.2.2.3.4.0 Cluster size: 40nodes About Application: We have an Apache Apex application, where in we have one of the programs, which runs in 3 instances and does PUT operations simultaneously on a same Hbase table. Application is running fine from 3 -4 days, Although application recovered automatically, want to know more details on these exceptions in the log: Caused by: java.io.InterruptedIOException: #2, interrupted. currentNumberOfTask=1 at org.apache.hadoop.hbase.client.AsyncProcess.waitForMaximumCurrentTasks(AsyncProcess.java:1661) at org.apache.hadoop.hbase.client.AsyncProcess.waitForAllPreviousOpsAndReset(AsyncProcess.java:1687) at org.apache.hadoop.hbase.client.BufferedMutatorImpl.backgroundFlushCommits(BufferedMutatorImpl.java:208) at org.apache.hadoop.hbase.client.BufferedMutatorImpl.flush(BufferedMutatorImpl.java:183) at org.apache.hadoop.hbase.client.HTable.flushCommits(HTable.java:1449) at org.apache.hadoop.hbase.client.HTable.put(HTable.java:1040) Thanks a lot in advance.
