Pengcheng Xiong commented on HIVE-10731:
----------------------------------------

Could you post the environment and the query that you run? I assume that this 
follows the standard practice when we pass conf. Another example is for 
quotedId in HiveLexer.g. cc'ing [~jpullokkaran]
{code}
public void setHiveConf(Configuration hiveConf) {
    this.hiveConf = hiveConf;
  }
  
  protected boolean allowQuotedId() {
    String supportedQIds = HiveConf.getVar(hiveConf, 
HiveConf.ConfVars.HIVE_QUOTEDID_SUPPORT);
    return !"none".equals(supportedQIds);
  }
{code}
