-----------------------------------------
Summary: Deadlock w/ multi writer
Key: HUDI-2573
URL: https://issues.apache.org/jira/browse/HUDI-2573
Project: Apache Hudi
Issue Type: Bug
Reporter: sivabalan narayanan
Assignee: sivabalan narayanan
Fix For: 0.10.0
With synchronous metadata patch, we added locking for cleaning and rollbacks.
but there are code paths, where we do double locking and hence it hangs or
fails after sometime.
inline cleaning enabled.
```
C1 acquires lock.
post commit -> triggers cleaning.
cleaning again tries to acquire lock when about to commit
and this is problematic.
```
Also, when upgrade is needed, we take a lock and rollback failed writes. this
again will run into issues w/ double locking.
