Description

Current version of simlejson budled with Ambari doesn't provide performance boost, as speedup lib is linked with libpython2.6, which caused slowness on cluster deployments and increasing the overall CPU resource usage.

Simplejson need to be updated to support python 2.7, specially speedup binding. As we supporting various distribs, we need to provide PyUnicodeUCS4/PyUnicodeUCS2 lib variations as well. In the future we need separate lib for ibm ppc

In addition, logging functionality should be added to agent, which will notify if the boost is used.

The way how logging should be done:

on Agent start with message like: "Available boosts for: simplejson, subproccess32"
