Lars Hofhansl commented on HBASE-8438:
--------------------------------------
Is this right?
{code}
+ Set<String> paths = new
HashSet<String>(conf.getStringCollection("tmpjars"));
+ if (paths.size() == 0) {
+ throw new IllegalArgumentException("Configuration contains no tmpjars.");
+ }
{code}
Will we always get an exception unless we provide tmpjars (which should be
optional)?
Apologies if I missed something obvious.

> For tools like pig and hive, blindly appending the full output of `bin/hbase
> classpath` to their own CLASSPATH is excessive. They already build CLASSPATH
> entries for hadoop. All they need from us is the delta entries, the
> dependencies we require w/o hadoop and all of it's transitive deps. This is
> also a kindness for Windows, where there's a shorter limit on the length of
> commandline arguments.
> See also HIVE-2055 for additional discussion.
