> The two values in [core-default.xml |
> https://hadoop.apache.org/docs/r2.7.1/hadoop-project-dist/hadoop-common/core-default.xml]
> are wrong.
> {{fs.s3a.multipart.purge.age}}
> {{fs.s3a.connection.timeout}}
> {{fs.s3a.connection.establish.timeout}}
> \\
> \\
> *1. {{fs.s3a.multipart.purge.age}}*
> (in both {{2.6.2}} and {{2.7.1}})
> In [core-default.xml |
> https://hadoop.apache.org/docs/r2.7.1/hadoop-project-dist/hadoop-common/core-default.xml],
> the value is {{86400}} ({{24}} hours), while in the code it is {{14400}}
> ({{4}} hours).
> \\
> \\
> *2. {{fs.s3a.connection.timeout}}*
> (only appear in {{2.6.2}})
> In [core-default.xml (2.6.2) |
> https://hadoop.apache.org/docs/r2.6.2/hadoop-project-dist/hadoop-common/core-default.xml],
> the value is {{5000}}, while in the code it is {{50000}}.
> {code}
> // seconds until we give up on a connection to s3
> public static final String SOCKET_TIMEOUT = "fs.s3a.connection.timeout";
> public static final int DEFAULT_SOCKET_TIMEOUT = 50000;
> {code}

> *3. {{fs.s3a.connection.establish.timeout}}*
> (only appear in {{2.7.1}})
> In [core-default.xml (2.7.1)|
> https://hadoop.apache.org/docs/r2.7.1/hadoop-project-dist/hadoop-common/core-default.xml],

> {code}
> \\
> btw, the code comments are wrong! The two parameters are in the unit of
> *milliseconds* instead of *seconds*...
> {code}
> - // seconds until we give up on a connection to s3
> + // milliseconds until we give up on a connection to s3
> ...
> - // seconds until we give up trying to establish a connection to s3
> + // milliseconds until we give up trying to establish a connection to s3
> {code}
