[jira] [Commented] (DRILL-7078) SqlLine: IOException: Resource temporarily unavailable

["Anton Gozhiy (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/DRILL-7078?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16785602#comment-16785602 ] 

Anton Gozhiy commented on DRILL-7078:
-------------------------------------

There are simpler steps: 
# Run Drill in embedded mode (no authentication settings are needed)
# Open the Web-UI (http://localhost:8047/)
# Run some query:
{code:java}
select * from cp.`tpch/nation.parquet`
{code}

Note: It is always reproducible the first time after starting Drill in embedded mode. To reproduce it again, restart Drill or wait for some timeout (several minutes).
