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'
## Work around is to restart sentry
To know if the issue is resolved, compare the max(NOTIFICATION_ID) from
SENTRY_HMS_NOTIFICATION_ID with max(EVENT_ID) from NOTIFICATION_LOG.They should
be equal

> 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.
