László Bodor commented on TEZ-4101:
-----------------------------------
unfortunately, Objects or other Java built-in classes don't have the
corresponding methods for checkArgument/checkState, so I will have to implement
them again in tez common Preconditions (right?)
https://github.com/google/guava/blob/master/guava/src/com/google/common/base/Preconditions.java
however, these are quite simple methods, so this implementation will be very
similar to Guava's, hope it's not an issue...
