Subject Re: Splitting causes HBase to crash
Date Fri, 13 May 2016 16:10:04 GMT
bq. 2016-05-13 11:56:52,763 WARN
org.apache.hadoop.hbase.master.SplitLogManager: error while splitting logs
in
[hdfs://ip-172-31-50-109.ec2.internal:8020/hbase/WALs/ip-
172-31-54-241.ec2.internal,60020,1463123941413-splitting]
installed = 1 but only 0 done

Looks like WAL splitting was slow or stalled.
Please check region server log to see why.

Cheers
