On CentoOS cluster Drill hangs while querying sys tables after "use dfs;" (embedded or distributed mode): {code} 0: jdbc:drill:> select * from sys.version; +----------+-------------------------------------------+------------------------------------------------------+----------------------------+--------------------+----------------------------+ | version | commit_id | commit_message | commit_time | build_email | build_time | +----------+-------------------------------------------+------------------------------------------------------+----------------------------+--------------------+----------------------------+ | 1.13.0 | 796fcf051b3553c4597abbdca5ca247b139734ba | [maven-release-plugin] prepare release drill-1.13.0 | 13.03.2018 @ 11:39:14 IST | par...@apache.org | 13.03.2018 @ 13:13:45 IST | +----------+-------------------------------------------+------------------------------------------------------+----------------------------+--------------------+----------------------------+ 1 row selected (3.784 seconds) 0: jdbc:drill:> use dfs; +-------+----------------------------------+ | ok | summary | +-------+----------------------------------+ | true | Default schema changed to [dfs] | +-------+----------------------------------+ 1 row selected (0.328 seconds) 0: jdbc:drill:> select * from sys.version; Error: Statement canceled (state=,code=0) 0: jdbc:drill:> {code} *Note*: there is not failure on local debian machine in embedded mode. dfs pugin configs are default (with "connection": "file:///", other file systems works good). This failure is connected to DRILL-5089 and calcite rebase.

After calcite validate "sys" SimpleCalciteSchema is created. But in WorkspaceSchemaFactory#create wrong WorkspaceConfig is left and "/" is combined with "sys". -- This message was sent by Atlassian JIRA (v7.6.3#76005)
