Namit Jain commented on HIVE-1978:
----------------------------------
Also, it might be simpler to add the new function 'getContentSummary' in all
existing
input formats.
You can create a dummy class which all other hive input formats (other than
symlinktextinputformat) extend.
In the abstract dummy class, the existing defn. can be there.
FileSystem fs = p.getFileSystem(ctx.getConf());
cs = fs.getContentSummary(p);
That waym you dont need any special checking in Utilities.java - it calls
getContentSummary(),
which is implemented by all input formats that hive supports.
> Hive SymlinkTextInputFormat does not estimate input size correctly
