Vaibhav Gumashta updated HIVE-21460: ------------------------------------ Attachment: HIVE-21460.1.patch > ACID: Load data followed by a select * query results in incorrect results > ------------------------------------------------------------------------- > > Key: HIVE-21460 > URL: https://issues.apache.org/jira/browse/HIVE-21460 > Project: Hive > Issue Type: Bug > Components: Transactions > Affects Versions: 4.0.0, 3.1.1 > Reporter: Vaibhav Gumashta > Assignee: Vaibhav Gumashta > Priority: Blocker > Attachments: HIVE-21460.1.patch > > > This affects current master as well. Created an orc file such that it spans > multiple stripes and ran a simple select *, and got incorrect row counts > (when comparing with select count(*). The problem seems to be that after > split generation and creating min/max rowId for each row (note that since the > loaded file is not written by Hive ACID, it does not have ROW__ID in the > file; but the ROW__ID is applied on read by discovering min/max bounds which > are used for calculating ROW__ID.rowId for each row of a split), Hive is only > reading the last split. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
