This warning message keeps appearing in the log during query execution.
Even if the invalidate metadata statement is done this warning does not dissapear.
Tried INVALIDATE METADATA xxxx
and as well INVALIDATE METADATA (without specif the table name)
Backend 1:Block locality metadata for table 'xxxx' may be stale. Consider running "INVALIDATE METADATA xxxx"
We have ran into the same problem as well (Impala v2.1.0-cdh5). Dropping and recreating the tables will temporarily remove these warnings, although they return after a few query executions. As Tomas mentioned, the INVALIDATE METADATA workflow has no effect here.
We recently upgraded to CDH 5.3.1 and started facing this issue, I have noticed that there is a BUG reported on this issue. Any luck with fixing this yet?
Hi all -
This sounds like IMPALA-1712. We believe that these error messages are mostly spurious (i.e. they're incorrectly printed). The next release of Impala has removed these messages.
