Masatake Iwasaki commented on HADOOP-17144:
-------------------------------------------
{quote}
we do have a test case similar to this scenario in
TestCompressorDecompressor#testCompressorDecompressorWithExeedBufferLimit ,
modified the lz4 constructors to use default buffer size
{quote}
[~hemanthboyina] Interestingly the test case does not cover the intended
scenario. I filed HADOOP-17270 for that. The 004 patch fails on the updated
test case. Reverting the change below fixed the failure.
