Scanner uses the "working" table name while everything else can still safely use the original configured table name. > Resolve table name to table id once in Accumulo input format > ------------------------------------------------------------ > > Key: ACCUMULO-1732 > URL: https://issues.apache.org/jira/browse/ACCUMULO-1732 > Project: Accumulo > Issue Type: Bug > Affects Versions: 1.4.0 > Reporter: Keith Turner > Assignee: Corey J. Nolet > Priority: Minor > > AccumuloInputFormat (and I suspect AccumuloOutputFormat) sends the table name to each mapper. The mapper uses this table name to create a scanner. In the case of the following events a map reduce job could read from two different table ids. > # start M/R job reading table A > # rename table A (tableId=1) to table C > # rename table B (tableId=2) to table A > If the input format passed table id 1 to the mappers, then the renames would not cause a problem. -- This message was sent by Atlassian JIRA (v6.1#6144)
