------------------------------------------------
Summary: Possible NegativeArraySizeException while scanning local
indexes during regions merge
Key: PHOENIX-3098
URL: https://issues.apache.org/jira/browse/PHOENIX-3098
Project: Phoenix
Issue Type: Bug
Reporter: Sergio Peleato
Assignee: Rajeshbabu Chintaguntla
Fix For: 4.8.0
While scanning local indexes during regions merge we might end up with
NegativeArraySizeException which leads to RS down. The reason for this is some
times HBase won't do real seek and considered fake keyvalues(can be scan start
row) as seeked kvs. In that case we ended up with this issue when we call peek
without seek. So for local indexes we need to enforce seek all the time for
scanning local index reference files.
