Hi,
IN PreBatchMutate method in Observer, I am trying to check whether a row ,
say '123', exists and delete the row. This row is different from the
current row , say '111' ,in the method, which has locked the current row.
But Delete operation is waiting for the lock to '111' instead of '123'.
Say, I have a table - test_delete, cf:delete_row
I have two rows 1) '123','defaultRow' 2) '111','111'
I will try to re-insert the second row with '111','123'. IN PreBatchMutate
method, I am trying to check if row '123' exists and delete it.
Result result = c.getEnvironment().getRegion().get(new
Get(Bytes.toBytes('123')));
byte[] deleteRow = result.getRow();
logger.debug(String.format("Deleting row
:%s", Bytes.toString(deleteRow)));
Delete delete = new Delete(deleteRow);
c.getEnvironment().getRegion().delete(delete);
Exception :
org.apache.hadoop.hbase.regionserver.HRegion: Failed getting lock in batch
put, row=111
java.io.IOException: Timed out waiting for lock for row: 111
Please advice.
