The "move" handles each 000000_N separately. The first on creates delta_00= 00019_0000019 under the table/partition dir, the others just add bucket_000= 0N there. That means there is a small window where someone may "ls table/part/delta_0= 000019_0000019" and not see all the buckets. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
