-----------------------------------------------------------------
I created this JIRA based on a support case in the Cloudera/Hortonworks
community forums.
I just stumbled across the answer to this.
The user is experiencing and issue because, for masking, the query is
manipulated to mask the appropriate values and then passed through the Hive
ANTLR SQL parser to be processed again. However, it fails because there is a
feature called {{hive.support.quoted.identifiers}}. This feature is enabled by
default, and it allows the original query to be parsed correctly. However,
this flag (via the session context) is not provided to the parser the second
time around and therefore the parser mishandles the backticks. If no context
is provided, the default behavior becomes "false".
{code:java|title=HiveLexer.g}
public void setHiveConf(Configuration hiveConf) {
this.hiveConf = hiveConf;
}
protected boolean allowQuotedId() {
if(hiveConf == null){
return false;
}
String supportedQIds = HiveConf.getVar(hiveConf,
HiveConf.ConfVars.HIVE_QUOTEDID_SUPPORT);
return !"none".equals(supportedQIds);
}
{code}
