----------------------------------
Summary: Crash when attempting split with
DelimitedKeyPrefixRegionSplitPolicy
Key: HBASE-8856
URL: https://issues.apache.org/jira/browse/HBASE-8856
Project: HBase
Issue Type: Bug
Affects Versions: 0.94.8
Reporter: Robert Dyer
I am using DelimitedKeyPrefixRegionSplitPolicy on my table. When I attempted
to split the table from the web interface, it gives the error below.
I believe the problem is
org.apache.hadoop.hbase.regionserver.DelimitedKeyPrefixRegionSplitPolicy.getSplitPoint:75
- the call from super.getSplitPoint() (line 71) returns null and this
condition is not checked.
