We have a CDH 4.2.0 Hadoop installation from tarballs and Impala 1.0
installation from RPM. I've decided to install libhadoop.so to Hadoop.
However, I don't want to build the library. Instead, I've copied it from
Impala to my Hadoop directory. So far I haven't seen any issues.
I am a bit worried whether what I did was correct. In this regard, I have
1. Is Impala 1.0 libhadoop.so 100% compatible with CDH Hadoop 4.2.0 ?
2. We are planning to upgrade to CDH 4.2.1 soon. Will libhadoop.so from
Impala 1.0 be compatible with CDH Hadoop 4.2.1?
