Change subject: IMPALA-9764: TransactionKeepalive should set sleep interval based on Hive Configuration ...................................................................... IMPALA-9764: TransactionKeepalive should set sleep interval based on Hive Configuration Impala must heartbeat its transactions and locks in order to keep them alive. Before this commit TransactionKeepalive had hard-coded value for sleep interval, i.e. it slept 60 seconds between heartbeats. However, at HMS side the transaction timeout is configurable. With this commit Impala reads the Hive configuration and calculate its sleep interval based on that. It simply divides the timeout value by 3. Testing: I tested it manually. Created hive-site.xml with "hive.txn.timeout" set and checked that Impala picked up the set value. If "hive.txn.timeout" was not set, Impala used the default value (300s).
