Subject org.apache.hadoop.hbase.regionserver.wal.DamagedWALException: Append sequenceId=8689
Date Thu, 06 Jul 2017 20:48:52 GMT
Hi All,

We are running HBase/Phoenix on EMR5.2(HBase1.2.3 and Phoenix4.7) and
we running into following exception when we are trying to load data
into one of our Phoenix table:
2017-07-06 19:57:57,507 INFO
[hconnection-0x60e5272-shared--pool2-t249]
org.apache.hadoop.hbase.client.AsyncProcess: #1, table=DE.CONFIG_DATA,
attempt=30/35 failed=38ops, last exception:
org.apache.hadoop.hbase.regionserver.wal.DamagedWALException:
org.apache.hadoop.hbase.regionserver.wal.DamagedWALException: Append
sequenceId=8689, requesting roll of WAL
	at org.apache.hadoop.hbase.regionserver.wal.FSHLog$RingBufferEventHandler.append(FSHLog.java:1921)
	at org.apache.hadoop.hbase.regionserver.wal.FSHLog$RingBufferEventHandler.onEvent(FSHLog.java:1773)

	at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617)
	at java.lang.Thread.run(Thread.java:745)

We are OK with wiping out this table and rebuilding the dataset. We
tried to drop the table and recreate the table but it didnt fix it.
Can anyone please let us know how can we get rid of above problem? Are
we running into https://issues.apache.org/jira/browse/HBASE-16960?
