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
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)
