| 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 | Description |
|---|---|
| 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.
