Jerome Boulon updated HADOOP-5100:
----------------------------------
Status: Patch Available (was: Open)
Set append flag to true.
>From log4j Doc API
/**
The <b>Append</b> option takes a boolean value. It is set to
<code>true</code> by default. If true, then <code>File</code>
will be opened in append mode by {...@link #setFile setFile} (see
above). Otherwise, {...@link #setFile setFile} will open
<code>File</code> in truncate mode.
<p>Note: Actual opening of the file is made when {...@link
#activateOptions} is called, not when the options are set.
*/

void setAppend(boolean flag) {
fileAppend = flag;
}
