Akira Ajisaka commented on HDFS-11195:
--------------------------------------
Thanks [~yuanbo] for reporting this and providing the patch. Now I have one
comment:
{code:title=HdfsWriter.java}
private void releaseDfsResourcesAndThrow() throws Exception {
cleanupAndThrow(LOG, out);
cleanupAndThrow(LOG, client);
}
{code}
If an exception is thrown when closing {{out}}, {{client}} won't be closed. I'd
like to re-use {{exceptionCaught}} to close them as follows:
{code:title=HdfsWriter#channelRead0}
} catch (Exception cause) {
exceptionCaught(ctx, cause);
}
{code}
> When appending files by webhdfs rest api fails, it returns 200
