How do you want to handle that _impala_signature() call? I can just update this PR for that if you want? Or we can incorporate into one of the other base_sql refactorings (i.e. removing duplicate functionality from base_sqlalchemy

Not so concerned about _impala_signature(). There is clearly something not right there, but it's probably not causing any bug or any problem. Feel free to h

Similar to how unix ls works, param could be -t

Given the new key-value store event stream, it'd be nice to have something like:

$ skein kv events <application id> [options...]

where the process blocks, and logs the event stream to the console until interrupted. This would be useful for debugging, as well as demos.

Assuming a valid hive-site.xml, it will be possible to determine the active hive warehouse HDFS directory and HiveServer2 and Metastore URIs.

From there we should be able to perform a directory analysis on the hive warehouse parent directory and then all HDFS locations that represent tables / partitions.
