Certain operations in HBase are known to directly affect the utilization of tables on HDFS. When these actions occur, we can circumvent the normal path and notify the Master directly. This results in a much faster response to changes in HDFS usage. This requires FS scanning by the RS to be decoupled from the reporting of sizes to the Master. An API inside each RS is made so that any operation can hook into this call in the face of other operations (e.g. compaction, flush, bulk load). Signed-off-by: Ted Yu <yuzhihong@gmail.com> |
