Arjun Mishra commented on SENTRY-2310:
--------------------------------------
Hi [~alexmc_bp]. You would have to upgrade Sentry to have this fix.
# What is the impact to users?
## Impact is on HDFS sync and HMS threads being blocked. You're Impala jobs are
probably running slow at this point. Sentry is not able to fetch or process any
notifications from HMS
# Are there any work-arounds or 'good behaviour' which
## Work around is to restart sentry
> Sentry is not be able to fetch full update subsequently, when there is HMS
> restart in the snapshot process.

> If the communication between sentry and HMS goes down for any reason while
> sentry is fetching full update from HMS, SentryHMSClient in HMSFollower would
> be left with a reference to closed socket. As sentry is not handling the
> failure and closing the SentryHMSClient, it continues using the same
> SentryHMSClient. This will result in "java.net.SocketException: Broken pipe"
> as the client tries to write on socket that is closed.
