----------------------------------
Summary: Throw exception which region is closing or splitting when
delete data
Key: PHOENIX-5860
URL: https://issues.apache.org/jira/browse/PHOENIX-5860
Project: Phoenix
Issue Type: Bug
Components: core
Affects Versions: 4.13.1
Reporter: Chao Wang
Attachments: PHOENIX.4.13.x-HBASE-1.3.x.001.patch
Currently delete data is UngroupedAggregateRegionObserver class on server
side, this class check if isRegionClosingOrSplitting is true. when
isRegionClosingOrSplitting is true, will throw new IOException("Temporarily
unable to write from scan because region is closing or splitting").
when region online , which initialize phoenix CP that
isRegionClosingOrSplitting is false.before region split, region change
isRegionClosingOrSplitting to true.but if region split failed,split will roll
back where not change isRegionClosingOrSplitting to false. after that all
write opration will always throw exception which is Temporarily unable to
write from scan because region is closing or splitting。
so we should change isRegionClosingOrSplitting to false when region
preRollBackSplit in UngroupedAggregateRegionObserver class。
A simple test where a data table split failed, then roll back success.but
delete data always throw exception.
# create data table
# bulkload data for this table
# alter hbase-server code, which region split will throw exception , then
rollback.
# use hbase shell , split region
# view regionserver log, where region split failed, and then rollback success.
# user phoenix sqlline.py for delete data, which will throw exption
