----------------------------------------
Summary: Flushing large compressed values can cause a crash
Key: KUDU-1524
URL: https://issues.apache.org/jira/browse/KUDU-1524
Project: Kudu
Issue Type: Bug
Components: cfile
Reporter: Jean-Daniel Cryans
Priority: Critical
It's possible right now to insert values that cannot be flushed. If a column is
configured to be compressed, the block compressor will limit blocks to 16MB so
if a large value isn't compressible, it won't be flushable. It will show up
like this in the log:
{noformat}
Invalid argument: Flush to disk failed: estimated max size 29545252 is greater
than the expected 16777216
{noformat}
Once this happens it's impossible to bring the server back since it will
bootstrap the tablet, try flushing again, and crash.
