> 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.");
