László Bodor commented on TEZ-4234:
-----------------------------------
[~gopalv]: I'm nott 100% sure, but seems like the case you mentioned applies
also to built-in zlib. With [^TEZ-4234.wip.patch] , I can see this on the
console ([written
here|https://github.com/apache/tez/blob/master/tez-runtime-library/src/test/java/org/apache/tez/runtime/library/common/sort/impl/TestIFile.java#L980-L981]),
wondering if this is the same behavior you mentioned:
{code}
2020-09-26 09:53:29,877 INFO [main] impl.TestIFile
(TestIFile.java:writeTestFile(962)) - Uncompressed: 36
2020-09-26 09:53:29,877 INFO [main] impl.TestIFile
(TestIFile.java:writeTestFile(963)) - CompressedSize: 46
{code}
> Compressor can cause IllegalArgumentException in Buffer.limit where limit
> exceeds capacity
