This can cause problems when there sub directories with in a directory. > This cause some users accidentally wipe out directories with very important data. We should ban CTAS with location to a non-empty directory. > Reproduce: > create table ctas1 > location '/Users/ychen/tmp' > as > select * from jsmall limit 10; > create table ctas2 > location '/Users/ychen/tmp' > as > select * from jsmall limit 5; > Both creates will succeed. But value in table ctas1 will be replaced by ctas2 accidentally. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
