Examples of org.apache.hadoop.hbase.util.CancelableProgressable

org.apache.hadoop.hbase.util.CancelableProgressable
Similar interface as {@link org.apache.hadoop.util.Progressable} but returnsa boolean to support canceling the operation.
Used for doing updating of OPENING znode during log replay on region open.

      // Instantiate the region.  This also periodically tickles our zk OPENING
      // state so master doesn't timeout this region in transition.
      region = HRegion.openHRegion(this.regionInfo, this.htd,
          this.rsServices.getWAL(), this.server.getConfiguration(),
          this.rsServices,
        new CancelableProgressable() {
          public boolean progress() {
            // We may lose the znode ownership during the open.  Currently its
            // too hard interrupting ongoing region open.  Just let it complete
            // and check we still have the znode after region open.
            return tickleOpening("open_region_progress");
