[jira] [Created] (HBASE-20846) Table's shared lock is not hold by sub-procedures after master restart

Summary: Table's shared lock is not hold by sub-procedures after
master restart
Key: HBASE-20846
URL: https://issues.apache.org/jira/browse/HBASE-20846
Project: HBase
Issue Type: Bug
Affects Versions: 2.1.0
Reporter: Allan Yang
Assignee: Allan Yang
Fix For: 3.0.0, 2.1.0, 2.0.2
Found this one when investigating ModifyTableProcedure got stuck while there
was a MoveRegionProcedure going on after master restart.
Though this issue can be solved by HBASE-20752. But I discovered something else.
Before a MoveRegionProcedure can execute, it will hold the table's shared lock.
so,, when a UnassignProcedure was spwaned, it will not check the table's shared
lock since it is sure that its parent(MoveRegionProcedure) has aquired the
table's lock.
{code:java}
// If there is parent procedure, it would have already taken xlock, so no need
to take
// shared lock here. Otherwise, take shared lock.
if (!procedure.hasParent()
&& waitTableQueueSharedLock(procedure, table) == null) {
return true;
}
{code}
But, it is not the case when Master was restarted. The child
procedure(UnassignProcedure) will be executed first after restart. Though it
has a parent(MoveRegionProcedure), but apprently the parent didn't hold the
table's lock.
So, since it began to execute without hold the table's shared lock. A
ModifyTableProcedure can aquire the table's exclusive lock and execute at the
same time. Which is not possible if the master was not restarted.
This will cause a stuck before HBASE-20752. But since HBASE-20752 has fixed, I
wrote a simple UT to repo this case.
I think we don't have to check the parent for table's shared lock. It is a
shared lock, right? I think we can acquire it every time we need it.

Summary: Duplicate rows returned while hbase snapshot reads
Key: HBASE-20844
URL: https://issues.apache.org/jira/browse/HBASE-20844
Project: HBase
Issue Type: Bug
Components: mapreduce, spark
Affects Versions: 1.3.1
Environment: Cluster Details
Java1.7
Hbase 1.3.1
Spark 1.6.1
Reporter: ShivaKumar SS
We are trying to take snapshot from code and read data using MR and spark, both
approaches are returning duplicate records.
On the API side, {{org.apache.hadoop.hbase.mapreduce.TableSnapshotInputFormat
}} is used.
Snapshot was taken during the table is being in the region split state.
We suspect it is due to data is being returned for both parent and daughter
regions.
