-----------------------------------
Summary: Streaming Ingest v2 does not send heartbeats
Key: HIVE-24077
URL: https://issues.apache.org/jira/browse/HIVE-24077
Project: Hive
Issue Type: Bug
Components: Streaming
Reporter: Matt Burgess
In Hive Streaming v2, TransactionBatch calls setupHeartbeatThread() before
setting minTxnId to an AtomicLong object, so the value that is used for
HeartbeatRunnable is null. Upon the first call to run(), a NullPointerException
is thrown by the minTxnId.get() call, which causes the thread to fail and it
does not get rescheduled. This causes any transaction that exceeds the
transaction timeout time (default 5 mins) to be aborted.
