[jira] [Created] (DRILL-7956) The web does not respond when there are too many queries

Hanoch Yang created DRILL-7956:
----------------------------------

             Summary: The web does not respond when there are too many queries
                 Key: DRILL-7956
                 URL: https://issues.apache.org/jira/browse/DRILL-7956
             Project: Apache Drill
          Issue Type: Bug
          Components: Client - HTTP
    Affects Versions: 1.18.0
            Reporter: Hanoch Yang


I used 1.18.0 to install the drill locally and installed an hbase storage plugin. When I executed the query continuously, when the fifth query was submitted, the REST API started to become unresponsive and the web page could not be accessed. After a few minutes, everything returned to normal. However, during this period of time, the REST API was unavailable, and the logs and system monitoring did not find any abnormalities. Why?
This is the query statement:
select * from `hbase`.`qqq` where CONVERT_FROM(`qqq`.c1.ip,'UTF8') = '10.38.12.94' and CONVERT_FROM(`qqq`.c1.`time`,'UTF8') >= '1621785600000' and CONVERT_FROM(`qqq`.c1.`time`,'UTF8') <= '1624464000000'
