--------------------------------------
Summary: 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
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.
