I'm no expert, but I don't think SELECTs are broken by an INSERT. See Locking <https://cwiki.apache.org/confluence/display/Hive/Locking> for details.
As I understand it, the INSERT needs an exclusive lock on the partition which it cannot get while the partition has a shared lock on it. Can someone confirm or correct this? -- Lefty On Fri, Apr 3, 2015 at 4:33 PM, Thomas Kwan <[email protected]> wrote: > Hi there, > > If we have multiple SELECTs going on for a table, will doing a "INSERT > OVERWRITE" to replace a partition break those SELECTs? > > thanks in advance > >
