chenglei updated HBASE-27062:
-----------------------------
Description: For master branch, {{HBaseInterClusterReplicationEndpoint}}
has already to use {{AsyncClusterConnection}} to send to peer cluster, but it
still use {{ThreadPoolExecutor}} to call
{{AsyncRegionServerAdmin.replicateWALEntry}} synchronously, I think we could
remove the {{ThreadPoolExecutor}} and call
{{AsyncRegionServerAdmin.replicateWALEntry}} using asynchronous style. (was:
