> 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: Gokul Gunasekaran
>
> 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"
> java.lang.RuntimeException: java.io.FileNotFoundException: File
> /cdap/tx.snapshot does not exist.
