Subject select count(1) : Cannot convert Indexed schema to NamePart
Date Wed, 28 Sep 2016 15:55:20 GMT
Hi,

 Since release 1.8,

we have a workspace hdfs.datarepo1 mapped to
/year/month/day/
containging csv.gz

if we do select count(1) on any level of the dir structure like
   select count(1) from hdfs.datarepo1.`/2016/08`;
We get
    Error: SYSTEM ERROR: IllegalStateException: You cannot convert a
indexed schema path to a   NamePart. NameParts can only reference Vectors,
not individual records or values.

same error with
   select count(1) from hdfs.datarepo1.`/` where dir0=2016 and dir1=08;


While this query works (or any select column)
   select count(column1) from hdfs.datarepo1.`/2016/08`;


Should I create a ticket?


Francois
