Subject [jira] [Commented] (KYLIN-3499) resource inconsistent caused by hbase rpc timeout
Date Tue, 21 Aug 2018 05:34:00 GMT


ASF GitHub Bot commented on KYLIN-3499:

momoxixi commented on issue #198: KYLIN-3499 Update
   In my Hadoop cluster, HDFS would occur `SLOW BlockReceiver xxx` sometimes, it  also made
HBase rpc slow. When HBase rpc timeout kylin rollback the resource timestamp but actually
HBase rpc already finished at server. So I added an another check to make sure HBase server
has not received that rpc.

> KYLIN use hbase to persist resouce metadata. When hbase rpc timeout, kylin would rollback
the resource timestamp. It caused resource inconsistent between kylin's memory and hbase if
hbase already put the resource.
