> Issue is related to Region Server being killed when one region is closing and another
region is trying to write index updates.
> When the data table region closes it will close region server level cached/shared connections
and it could interrupt other region index/index-state update.
> -- Region1: Closing
> {code:java}
> TrackingParallellWriterIndexCommitter#stop() {
> this.retryingFactory.shutdown();
> this.noRetriesFactory.shutdown();
> }{code}
> closes the cached connections calling CoprocessorHConnectionTableFactory#shutdown() in
ServerUtil.java
>  
> --Region2: Writing index updates
> Index updates fail as connections are closed, which leads to RejectedExecutionException/Connection
being null. This triggers PhoenixIndexFailurePolicy#handleFailureWithExceptions that tries
to get the the syscat table using the cached connections. Here it will not be able to reach
to SYSCAT , so we will trigger KillServreFailurePolicy.
> CoprocessorHConnectionTableFactory#getTable()
>  
>  
> {code:java}
> if (connection == null || connection.isClosed()) {
> throw new IllegalArgumentException("Connection is null or closed.");
> }{code}
