Todd Lipcon commented on HADOOP-8537:
-------------------------------------
I think this is failing for similar reasons to HADOOP-7111. That patch added
the following:
{code}
private int records1stBlock = NativeCodeLoader.isNativeCodeLoaded() ? 5674 :
4480;
private int records2ndBlock = NativeCodeLoader.isNativeCodeLoaded() ? 5574 :
4263;
{code}
But the condition is wrong. If the native libs are present but they don't have
gzip support compiled in (eg the gzip devel libraries weren't present at
compile time), then it should use the non-native expected values. Instead we
should check specifically for the zlib native code.
