----------------------------------------
Summary: TransactionStateCache service fails to startup if
data.tx.snapshot.dir does not exist
Key: TEPHRA-218
URL: https://issues.apache.org/jira/browse/TEPHRA-218
Project: Tephra
Issue Type: Bug
Reporter: Gokul Gunasekaran
Assignee: Poorna Chandra
If the data.tx.snapshot.dir doesn't exist, the TransactionStateCache fails to
startup since the refreshState() during startup() will throw
FileNotFoundException and it will cause the Service to stop. But it is handled
by just logging a message during every refresh.
Stack Trace:
{code}
Exception in thread "DefaultTransactionStateCache STARTING"

/cdap/tx.snapshot does not exist.
