> 1) HRegionServer#closeRegion(final RpcController controller,
> final CloseRegionRequest request)
> {code}
> // Can be null if we're calling close on a region that's not online
> final HRegion region = this.getFromOnlineRegions(encodedRegionName);
> if ((region != null) && (region .getCoprocessorHost() != null)) {
> region.getCoprocessorHost().preClose(false);
> }
> {code}
> 2) HRegionServer#closeRegion(String encodedName, final boolean abort,
> final boolean zk, final int versionOfClosingNode, final ServerName sn)
> {code}
> if ((actualRegion != null) && (actualRegion.getCoprocessorHost() != null)) {
> try {
> actualRegion.getCoprocessorHost().preClose(false);
> } catch (IOException exp) {
> LOG.warn("Unable to close region: the coprocessor launched an error ", exp);
> return false;
> }
> }
> {code}
> 3) HRegion# private List<StoreFile> doClose(
> final boolean abort, MonitoredTask status)
> {code}
> if (coprocessorHost != null) {
> status.setStatus("Running coprocessor pre-close hooks");
> this.coprocessorHost.preClose(abort);
> }
> {code}
> IMO 3rd one is enough and remaining two are not needed.
