Subject [jira] Commented: (HIVE-519) Regex processing gets stuck when querying weblogs
Date Thu, 28 May 2009 11:26:45 GMT

    [ https://issues.apache.org/jira/browse/HIVE-519?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12713947#action_12713947
] 

Johan Oskarsson commented on HIVE-519:
--------------------------------------

127.0.0.1 - - [26/May/2009:00:00:00 +0000] "GET /someurl/?track=Blabla(Main) HTTP/1.1" 200
5864 - "Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US) AppleWebKit/525.19 (KHTML, like Gecko)
Chrome/1.0.154.65 Safari/525.19"

Example of a line that takes 15 seconds to process on my machine, it does eventually complete
though. If I remove the (Main) part of the url it takes 29 milliseconds to finish.
