Jason Lowe updated HADOOP-9233:
-------------------------------
Status: Open (was: Patch Available)
Thanks for the update, Vadim. Another issue I ran into while trying out the
patch is running the unit tests when native code support is not compiled.
TestCompressorDecompressor fails in this case:
{noformat}
java.lang.UnsatisfiedLinkError:
org.apache.hadoop.io.compress.zlib.ZlibCompressor.init(III)J
at org.apache.hadoop.io.compress.zlib.ZlibCompressor.init(Native Method)
at
org.apache.hadoop.io.compress.zlib.ZlibCompressor.<init>(ZlibCompressor.java:228)
at
org.apache.hadoop.io.compress.zlib.ZlibCompressor.<init>(ZlibCompressor.java:198)
at
org.apache.hadoop.io.compress.TestCompressorDecompressor.testCompressorDecompressor(TestCompressorDecompressor.java:44)
{noformat}
We can't construct a {{ZlibCompressor}} or {{ZlibDecompressor}} without native
code support, which is why {{ZlibFactory}} hides this in its
{{getZlibCompressor}} and {{getZlibDecompressor}} methods. We either need to
use those methods (with conf settings to get the two types we want) or have the
code conditionally exclude the native codec support based on
{{ZLibFactory#isNativeZlibLoaded}}.
Arguably the acceptor function should also be checking this otherwise we run
the risk of the native code being loaded but zlib libraries are for some reason
unavailable.
