> Several HDFS client integer configs report raw NumberFormatException for
> out-of-range values

>
> Key: HDFS-17946
> URL: https://issues.apache.org/jira/browse/HDFS-17946
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: hdfs-client
> Reporter: jiang he
> Priority: Trivial
> Labels: pull-request-available
>
> Several HDFS client integer configuration keys fail with a raw
> NumberFormatException when set to an out-of-range negative value.
> Instead of exposing a raw NumberFormatException, HDFS should report a clear
> configuration validation error that identifies the invalid key and expected
> range.
> Examples
> Example 1
> <property>
> <name>dfs.client.block.write.retries</name>
> <value>-4294967296</value>
> </property>
> Observed:
> Failed to initialize filesystem hdfs://127.0.0.1:9000:
> java.lang.NumberFormatException: For input string: "-4294967296"
> Example 2
> <property>
> <name>dfs.client.pipeline.recovery.max-retries</name>
> <value>-4294967296</value>
> </property>
> Observed:
> Failed to initialize filesystem hdfs://127.0.0.1:9000:
> java.lang.NumberFormatException: For input string: "-4294967296"
> Example 3
> <property>
> <name>dfs.client.retry.max.attempts</name>
> <value>-4294967296</value>
> </property>
> Observed:
> Failed to initialize filesystem hdfs://127.0.0.1:9000:
> java.lang.NumberFormatException: For input string: "-4294967296"
> Example 4
> <property>
> <name>dfs.client.congestion.backoff.mean.time</name>
> <value>-4294967296</value>
> </property>
> Observed:
> java.lang.NumberFormatException: For input string: "-4294967296"
> Expected
> HDFS should report clear configuration validation errors, for example:
> Invalid value for dfs.client.block.write.retries: -4294967296.
> The value must be a valid integer within range ...
> rather than a raw NumberFormatException.
> Control test
> The following normal values pass successfully:
> <property>
> <name>dfs.client.block.write.retries</name>
> <value>3</value>
> </property>
> <property>
> <name>dfs.client.pipeline.recovery.max-retries</name>
> <value>5</value>
> </property>
> <property>
> <name>dfs.client.retry.max.attempts</name>
> <value>10</value>
> </property>
> <property>
> <name>dfs.client.congestion.backoff.mean.time</name>
> <value>5000</value>
> </property>
