[jira] [Created] (HDDS-6474) File system optimized bucket list status file number inconsistent

mengqi created HDDS-6474:
----------------------------

             Summary: File system optimized bucket list status file number inconsistent
                 Key: HDDS-6474
                 URL: https://issues.apache.org/jira/browse/HDDS-6474
             Project: Apache Ozone
          Issue Type: Bug
    Affects Versions: 1.2.0
            Reporter: mengqi


I put 10000 file （file name is 0001 - 10000） to a File system optimized bucket dir /user/filesystemoptimizedbucket/test and list the dir ，found something wrong. 

./bin/ozone fs -ls /user/filesystemoptimizedbucket/test | wc -l 

only 5000+ files found , not 10000。 so  I read the source code ,and found the issue in the function org.apache.hadoop.ozone.om.KeyManagerImpl#getFilesFromDirectory 

after listStatusFindFilesInTableCache,   countEntries should be set into 0. so we can find all files from keyTable.iterator . 

I fix the issue, someone can review it ?
