ErrorHeuristic | Classes implementing ErrorHeuristic are able to generate a possible cause and solution for Hive jobs that have failed by examining the query, task log files, and the job configuration. |
Class Summary | |
---|---|
DataCorruptErrorHeuristic | Detects the condition where there is a error with one of the input files in the query. |
ErrorAndSolution | Immutable class for storing a possible error and a resolution suggestion. |
MapAggrMemErrorHeuristic | Detects out-of-memory errors when hash tables in map-based aggregation group by queries take up too much memory. |
RegexErrorHeuristic | Simple heuristic where the query and the lines of the task log file are run through regular expressions to see if they resemble a known error condition. |
ScriptErrorHeuristic | Detects when a query has failed because a user's script that was specified in transform returns a non-zero error code. |
TaskLogProcessor | TaskLogProcessor reads the logs from failed task attempts and tries to figure out what the cause of the error was using various heuristics. |
Generates execution error messages using heuristics.
