Eric Yang commented on CHUKWA-583:
----------------------------------
This bug is in the test code, and we don't push large amount of data over the
validation framework. Hence, it is a minor bug. Patch to increase the size is
welcome.
> Copying data from inputStream to OuputStream needs appropriate buffer size

> Key: CHUKWA-583
> URL: https://issues.apache.org/jira/browse/CHUKWA-583
> Project: Chukwa
> Issue Type: Bug
> Components: Data Processors
> Affects Versions: 0.4.0
> Reporter: Xiaoming Shi
> Priority: Trivial
>
> In the file
> ./chukwa-0.4.0/src/test/org/apache/hadoop/chukwa/validationframework/util/DataOperations.java
> line: 54-58
> In the function copyFile, the buffer size is fixed as 4096 bytes. With the
> size of the data varies, the performance can be damaged a lot.
> We need an appropriate buffer size which depends on the size of the data to
> be copied.
> This is the same as the Appache Bug
> (https://issues.apache.org/bugzilla/show_bug.cgi?id=32546)
