Alicia Ying Shu commented on PHOENIX-1356:
------------------------------------------
[~rajesh23] We can keep my original fix using Admin for the following reasons:
1) The Meta only records the beginning state and finished state of a split.
There is no intermediate state recorded. So before the split completes, the
number of regions will be 4, after the split the number of regions will be 4+i.
We can use Admin to get this info.
2) There will be side-effect using MetaReader#getTableRegions(CatalogTracker
catalogTracker,TableName tableName, final boolean excludeOfflinedSplitParents)
setting excludeOfflinedSplitParents=false. After a split finished, the Parent
region info would stay there until CatalogJanitor removes it. During this
period, the number of region is 4+i+1. But the split already finished. The test
may waiting longer than necessary inside the loop (regionNumber != 4+i). If
using Admin, we will exit the loop once the split finishes.
3) MetaReader is private. Better not calling it directly.
Thanks.
