-------------------------------------
was (Author: JIRAUSER298470):
*Root Cause:*
When the query node starts, it assigns the value of metadata.url to
queryHistory.url, then sets metadata.url to HDFS. However, in the recommended
code, the value of metadata.url is mistakenly assigned to JdbcQueryHistory.url,
and then metadata.url is set to HDFS. Afterward, the modified metadata.url is
reassigned to queryHistory.url. This causes queryHistoryStore to use the HDFS
address, leading to errors.
*Fix Design:*
Since JdbcQueryHistory.url is not actually used, simply remove it and restore
the original logic.
