bvaradar opened a new pull request #1229: [HUDI-535] Ensure Compaction Plan is 
always written in .aux folder to avoid 0.5.0/0.5.1 reader-writer compatibility 
issues
URL: https://github.com/apache/incubator-hudi/pull/1229
 
 
   
   ## What is the purpose of the pull request
   
   PR #1009 introduces table layout version which is used to determine if 
rename must be allowed or not. Renames are disabled by default in 0.5.1 but 
users can enable them in ingestion through write config. Along with this 
feature, another related change to avoid writing compaction plans in .aux 
folder is added. This change could result in race conditions when we use 
different versions for reader and writer. This PR effectively reverts the 
compaction plan storage change allowing it to be also stored in .aux folder.
