[GitHub] [iotdb] MarcosZyk opened a new pull request, #6428: [IOTDB-3260] Fix npe while concurrent delete storage group

MarcosZyk opened a new pull request, #6428:
URL: https://github.com/apache/iotdb/pull/6428

   ## Description
   
   
   ### NPE Cause
   
   When executing predelete and delete sg on partitionInfo, the target storageGroupPartitionTable will be taken from a concurrentHashMap. If the deletion is executed concurrently, the taken table may be null since there may be some thread else delete the table, which may results in NPE if there's no check.
   
   ### Solution
   Before invoke any interface of storageGroupPartitionTable taken from the map, check whether the table is null.
