Samarth Jain created PHOENIX-3448:
-------------------------------------
Summary: Possible deadlock because transaction service client is
stuck
Key: PHOENIX-3448
URL: https://issues.apache.org/jira/browse/PHOENIX-3448
Project: Phoenix
Issue Type: Bug
Reporter: Samarth Jain
I have noticed on my local test run that sometimes IndexExtendedIT isn't
completing. On taking a thread dump, I am seeing two threads waiting for the
lock (waiting to lock <0x0000000788e69f50>) as follows:
{code}
"StoreFileOpenerThread-0-1" daemon prio=5 tid=0x00007fc796e43800 nid=0x2631f
waiting for monitor entry [0x0000000128f62000]

The thread which has the lock is stuck because starting the transaction client
service hasn't returned. The stacktrace for that thread looks like this:
{code}
