---------------------------------
Summary: The force update thread may have race with PE worker when
the procedure is rolling back
Key: HBASE-21351
URL: https://issues.apache.org/jira/browse/HBASE-21351
Project: HBase
Issue Type: Sub-task
Components: proc-v2
Reporter: Duo Zhang
Fix For: 3.0.0, 2.2.0, 2.1.1, 2.0.3
We will acquire the procExecutionLock for a procedure when force updating its
state to prevent race with PE worker, but this does not work then the procedure
is rolling back.
If a procedure is failed, we will mark the root procedure stack as FAILED, and
then start to rollback the whole procedure stack. We will pop every procedure
in the stack and try to rollback them. So we may change the state of a
procedure without holding its procExecutionLock when rolling back.
This means we may persist an intermediate state of a procedure and cause
corruption when loading procedures.
