Hi, I'm facing the following problem : When I run SHOW queries through HortonWorks ODBC Driver with my kerberos-enable cluster, it returns an empty result (there is no error, just an empty result). However, I can perform SELECT queries, I can also run CREATE DATABASE or CREATE TABLE queries. Note : I can perform SHOW queries using beeline client. Note 2 : I tried to activate TRACE logging for the driver, and I get one error : "Sep 28 18:48:03.508 ERROR 2741458688 Connection::SQLSetConnectAttr: [Hortonworks][ODBC] (11470) Transactions are not supported." Any idea ? Thanks in advance, Sylvain. ... View more

The alert is the following : Capacity Used:[100%, 36864], Capacity Remaining:[0] The thing is that I have set 300000000000 bytes of capacity for HDFS (property "Reserved space for HDFS"), so I can't see where my problem is ...
