Steve Loughran commented on HADOOP-13680:
-----------------------------------------
checkstyle is line length:
{code}
./hadoop-tools/hadoop-aws/src/main/java/org/apache/hadoop/fs/s3a/S3AFileSystem.java:189:
readAhead = longByteOption(conf, READAHEAD_RANGE,
DEFAULT_READAHEAD_RANGE, 0);: Line is longer than 80 characters (found 84).
{code}
I'll fix that on the commit. Local test verified this BTW, S3 Ireland, with the
-Pscale profile for scale tests too, as these play with the numbers.
> fs.s3a.readahead.range to use getLongBytes

> The {{fs.s3a.readahead.range}} value is measured in bytes, but can be
> hundreds of KB. Easier to use getLongBytes and set to things like "300k"
> This will be backwards compatible with the existing settings if anyone is
> using them, because the no-prefix default will still be bytes
