Hani Nadra updated HBASE-12445:
-------------------------------
Attachment: 0001-HBASE-11788-hbase-is-not-deleting-the-cell-when-a-Pu.patch
Here the patch with the updated test and the fix suggest by sri in 1178:
QualifierValue.Builder valueBuilder = QualifierValue.newBuilder(); at line
number 1110 should be inside the inner for loop at 1115. Otherwise valueBuilder
is carrying over the previous values that where set. In this case the
DeleteType is getting carried over to the next columns and deleting all the
columns. Attached the testcase to the defect.Could you please reopen the defect.
> hbase is removing all remaining cells immediately after the cell marked with
> marker = KeyValue.Type.DeleteColumn via PUT
