> When a single file of Hbase metadata is greater than a certain value, the file is sunk
into HDFS for storage. When files in execute_output/ are deleted in HDFS, the monitoring page
will not display any tasks.

> {color:#24292e}2.Modify the hbase configuration ,configure "hbase.client.keyvalue.maxsize"
into a small value, such as 524288.{color}
> {color:#24292e}3.Create a new build task, after the build task finished,find the /execute_output
hbase metadata path on HDFS, /\{working_dir}/\{metadata_url}/resources/execute_output/...,
and delete one of the files.{color}
