Akira AJISAKA commented on HADOOP-11627:
----------------------------------------
bq. It's the same for bzip2.
Rethinking this, it's not the same.
* ZlibFactory tries to load native library when the class is initialized. (only
once)
* Bzip2Factory tries to load native library when
{{isNativeBzip2Loaded(Configuration)}} is called. (not only once)
I don't see any existing tests for non-native bzip2 (dummy) library, so we
don't need to introduce a setter method for Bzip2Factory. For non-native gzip
library, setting {{ZlibFactory.nativeZlibLoaded}} to false is sufficient.
Sorry for the confusion.
