Master can't split logs created by THBase
-----------------------------------------
Key: HBASE-1858
URL: https://issues.apache.org/jira/browse/HBASE-1858
Project: Hadoop HBase
Issue Type: Bug
Components: master
Affects Versions: 0.20.0
Reporter: Clint Morgan
Assignee: Clint Morgan
Fix For: 0.20.1, 0.21.0
When master tries to split logs created by THbase, it fails because it tries to
read in the wrong key type. (THBase subclasses HLogKey to add fields to the
key).
