default void preCleanupBulkLoad(ObserverContext<RegionCoprocessorEnvironment> ctx)
    throws IOException {
  }
Called as part of SecureBulkLoadEndpoint.cleanupBulkLoad() RPC call. It can't bypass the
default action, e.g., ctx.bypass() won't have effect. If you need to get the region or table
name, get it from the <code>ctx</code> as follows:
<code>code>ctx.getEnvironment().getRegion()</code>. Use getRegionInfo to fetch the encodedName
and use getDescriptor() to get the tableName.
@param ctx the environment to interact with the framework and master
