hemantk-12 opened a new pull request, #7991:
URL: https://github.com/apache/ozone/pull/7991

   ## What changes were proposed in this pull request?
   As part of change #4680, BootstrapStateHandler was introduced to synchronize 
tarball creation with background services. 
   The problem is that SnapshotDeletingService doesn't use implemented 
BootstrapStateHandler.Lock rather creates a new lock every time. This means 
tarball creation will never be synchronized on the same lock as 
SnapshotDeletingService.
   This change includes:
   1. Use 
[this](https://github.com/apache/ozone/blob/f7e9aedf49e005f219845f2911b92f66cec24bcf/hadoop-ozone/ozone-manager/src/main/java/org/apache/hadoop/ozone/om/service/AbstractKeyDeletingService.java#L643)
 BootstrapStateHandler.Lock for moving, purging, and tarball creation.
   2. Added a wait for a response otherwise some transactions may be in Ratis 
logs that are neither applied nor in DoubleBuffer and can cause a race 
condition.
   3. SnapshotDirectoryCleaningService is also added to the required locks list 
for OMDBCheckpointServlet but it doesn't do any operation on Snapshotted DB so 
there is no change in SnapshotDirectoryCleaningService.
