xiarixiaoyao opened a new pull request #4139:
URL: https://github.com/apache/hudi/pull/4139
…eated by HoodieMergedLogRecordSanner when the query finished.
## *Tips*
RealtimeCompactedRecordReader should close deltaRecordMap when the query
finished to clear tmp file。
now HoodieMergedLogRecordScanner will create a tmp dir for read log. this
file will be deleted only when the jvm exit.
for presto/ hive local query（hive server deal those query）, the query jvm
will not exit。 with more and more query happen， the tmp dir will become more
and more larger。
before patch
step1: start beeline
step2: repeated execute: select * from lj_rt limit 1
step3: cd /tmp we found many hudi-BITCAST-xxxxx dir
