> Project: Phoenix

> 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
