Add global ID server into SSCC

The startId and commitId are now generated by a global ID server so

they are the same throughout the cluster. Without a global server

queries that spanned 2 region servers would return inconsistent results

Option to use ConcurrentHashMap vs synchronizedSet

Default is synchronizedSet

Option is set in ms.env


The synchronization option is for the participatingRegions

list in the client-side TransactionState.

We are seeing an issue where a duplicate region is being

inserted into the particpant list and it is possible that a

synchronizedSet is not blocking concurrent access as we

Adding separate pending txn wait for preSplit

Pending wait does not have limit, will wait until

pending transactions have completed.

Also adding new properties to customize behavior:


-If 'true' then split operation will not wait on

active transactions to complete. Will wait on

pending transactions. Default is 'false'

-Sets time in milliseconds that the preSplit

observer will poll for the active transaction

list to be empty. Default is 15000 (15 seconds)


-Sets time in milliseconds that the preSplit

observer will poll for the pending transaction

list to be empty. Default is 500 (0.5 seconds)

DDL Tx, Changes to handle upsert using load operations on abort

SQL statements 'upsert using load' will be executed outside of a

transaction even though the operation can performed inside a

transaction. For this reason, it is necessary for us to handle this

data differently when a transaction aborts or fails.

These operations will be registered as part of the TmDDL manager

and if the transaction is aborted, that table gets truncated. The data

loaded will be deleted but table will still exist. At the moment, this is

handled by using disable, delete and create hbase methods. However, when

hbase is upgraded to the next version, we will use the truncate hbase

method option.

Bug 1454034

This corrects a defect where the region would erroneously set the

TransactionState to aborted after already voting to commit it. This is

a violation of 2PC and would result in data inconsistency.

Batch2PC Endpoint Coprocessor Phase 1: Server API

Change-Id: I26bc73e6c9e84053bf8ca8e154eb2bd28fef0810

ClientSide batch RegionServer 2-phase commit calls

Disabled by default, use the option in ms.env to enable:


Included in this change are the server-side stubs which

are needed for building as new protocol buffers have

been added to support the multiple regionserver sets

of names. Server-side changes will be added later.

Basic design: On the client-side we have a list of

all the regions we need to communicate with. On prepare/

commit/abort we send those calls out individually by region.

This change will group the region names per regionserver

into one protocol buffer and include that in the RPC

call to the server.

Error handling is done by collecting the problematic

regions into a separate list in the TransactionState.

These 'retry' regions are then retried using the

single-region calls.

Implemented coprocessor calls using single-region method.

Adding a configurable region split delay limit

Configuration property that can be set in hbase-site.xml is:


Default will be 360, which is a 6 hour delay max.

When the delay limit is surpassed, the HBase splits will

no longer be blocked from the TM perspective. HBase may

still have delays due to GC or other operations.

Adding break out of preSplit() loop on exception

Also commenting out log message that is filling up client-side

logs even if there is no activity. The zookeeper message will

still be printed as DEBUG to show if the ZNode is not present.

The break of out preSplit() was needed as on a RS abort, the

preSplit can get stuck in a state where it is keeping the RS

process up and in a while/sleep loop.
