Xuefu Zhang commented on HIVE-18283: ------------------------------------ Patch looks good to me except for a minor improvement on a faster match() with precompiled patterns. > Better error message and error code for HoS exceptions > ------------------------------------------------------ > > Key: HIVE-18283 > URL: https://issues.apache.org/jira/browse/HIVE-18283 > Project: Hive > Issue Type: Improvement > Components: Spark > Reporter: Chao Sun > Assignee: Chao Sun > Attachments: HIVE-18283.0.patch, HIVE-18283.1.patch, > HIVE-18283.2.patch > > > Right now HoS only use a few error codes. For the majority of the errors, > user will see an error code 1 followed by a lengthy stacktrace. This is not > ideal since: > 1. It is often hard to find the root cause - sometimes it is hidden deeply > inside the stacktrace. > 2. After identifying the root cause, it is not easy to find a fix. Often user > have to copy & paste the error message and google them. > 3. It is not clear whether the error is transient or not, depending on which > user may want to retry the query. > To improve the above, this JIRA propose to assign error code & canonical > error messages for different HoS errors. We can take advantage of the > existing {{ErrorMsg}} class. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
