[jira] [Created] (IMPALA-9764) TransactionKeepalive should set sleep interval based on Hive Configuration

Zoltán Borók-Nagy created IMPALA-9764:
-----------------------------------------

             Summary: TransactionKeepalive should set sleep interval based on Hive Configuration
                 Key: IMPALA-9764
                 URL: https://issues.apache.org/jira/browse/IMPALA-9764
             Project: IMPALA
          Issue Type: Bug
            Reporter: Zoltán Borók-Nagy


Impala must heartbeat its transactions and locks in order to keep them alive.

Currently TransactionKeepalive has hard-coded value for sleep interval, i.e. it always sleeps 60 seconds between heartbeats.

However, at HMS side the time after which transactions are declared aborted if the client has not sent a heartbeat is configurable.

Impala should read the Hive configuration and calculate its sleep interval based on that.
