Subject [jira] [Commented] (HIVE-14538) beeline throws exceptions with parsing hive config when using !sh statement
Date Wed, 31 Aug 2016 02:04:20 GMT

    [ https://issues.apache.org/jira/browse/HIVE-14538?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15450781#comment-15450781
] 

Chaoyu Tang commented on HIVE-14538:
------------------------------------

The patch looks good. I wonder if the following code has the indention issue? 
{code}
+      if (dbconn != null)
+        conn = dbconn.getConnection();
+      if (conn != null) {     //should there be two spaces indention?
+        if (call) {
+          stmnt = conn.prepareCall("set");
+          hasResults = ((CallableStatement) stmnt).execute();
+        } else {
+          stmnt = beeLine.createStatement();
+          hasResults = stmnt.execute("set");
+        }
{code}
Also regarding your comment about that the variableSubstitution, can not following happen
at the Beeline (client site) and the value does not have to be the server value.
set variableX = valueX
select * from tbl where col1 = $variableX
I am just curious. The question is actually beyond the scope of the patch
