---------------------------------
Summary: HFileReader get split point handle empty HFile better
Key: HBASE-23271
URL: https://issues.apache.org/jira/browse/HBASE-23271
Project: HBase
Issue Type: Improvement
Components: regionserver
Affects Versions: 1.1.7, 3.0.0
Reporter: qiang Liu
Assignee: qiang Liu
currenttly if we call org.apache.hadoop.hbase.io.hfile.HFileReaderImpl#midKey
on an empty HFile, we got an exception like
java.io.IOException: HFile empty
since the function return an Optional<Cell> , I think it's better return
Optional.empty() instead of throw An Exception
when a region with muiltiple column family grow big enough to be splited, if
got some empty column family, will got some warn log like this
java.io.IOException: HFile empty at
org.apache.hadoop.hbase.io.hfile.HFileBlockIndex$BlockIndexReader.midkey(HFileBlockIndex.java:334)
sinece exception is catched, split logic will go on and got right result
