DRILL-3898 : Sort spill was modified to catch all errors, ignore repâ¦
â¦eated errors while closing the new group and issue a more detailed error
message.
Seems that the spilling IO can run into various kinds of errors (no space,
failure to create a file,..) which are thrown as different exception classes.
Hence changed the catch() statement to catch a more general Throwable , and add
the exception's message for more detail (e.g., no disk space).
Before the change the "no disk space" Throwable was not caught, and thus
execution continued.
Also the closing of the newGroup could hit some IO errors (e.g., when
flushing), so a try/catch was added to ignore those.
Note that this change should also fix DRILL-4542 ("if external sort fails
to spill to disk, memory is leaked and wrong error message is displayed").
