|

|
|
|
+We traced it down to the reader trying to read the file type of the next file but where it reads is still log data from the previous file. What happened was the Log Length was written as a certain size but the log data was actually longer then that.
|
|
|
+
|
|
|
+Inside of the write() routine in LogValue it first writes what the logfile length is, but then when it goes to write the log itself it just goes to the end of the file. There is a race condition here where if someone is still writing to the file when it goes to be aggregated the length written could be to small.
|
|
|
+
|
|
|
+We should have the write() routine stop when it writes whatever it said was the length. It would be nice if we could somehow tell the user it might be truncated but I'm not sure of a good way to do this.
|
|
|
+
|
|
|
+We also noticed that a bug in readAContainerLogsForALogType where it is using an int for curRead whereas it should be using a long.
|
|
|
+
|
|
|
+ while (len != -1 && curRead < fileLength) {
|
|
|
+
|
|
|
+This isn't actually a problem right now as it looks like the underlying decoder is doing the right thing and the len condition exits.</blockquote></li>

This limits each component of a file system path to a maximum of 255 bytes in UTF-8 encoding. Attempts to create new files that violate this rule will fail with an error. Existing files that violate the rule are not effected. Previously, dfs.namenode.fs-limits.max-component-length was set to 0 (ignored). If necessary, it is possible to set the value back to 0 in the cluster's configuration to restore the old behavior.</blockquote></li>

+ <b>Support 'hedged' reads in DFSClient</b><br>
|
|
|
+ <blockquote>If a read from a block is slow, start up another parallel, 'hedged' read against a different block replica. We then take the result of which ever read returns first (the outstanding read is cancelled). This 'hedged' read feature will help rein in the outliers, the odd read that takes a long time because it hit a bad patch on the disc, etc.
|
|
|
+
|
|
|
+This feature is off by default. To enable this feature, set <code>dfs.client.hedged.read.threadpool.size</code> to a positive number. The threadpool size is how many threads to dedicate to the running of these 'hedged', concurrent reads in your client.
|
|
|
+
|
|
|
+Then set <code>dfs.client.hedged.read.threshold.millis</code> to the number of milliseconds to wait before starting up a 'hedged' read. For example, if you set this property to 10, then if a read has not returned within 10 milliseconds, we will start up a new read against a different block replica.
|
|
|
+
|
|
|
+This feature emits new metrics:
|
|
|
+
|
|
|
++ hedgedReadOps
|
|
|
++ hedgeReadOpsWin -- how many times the hedged read 'beat' the original read
|
|
|
++ hedgedReadOpsInCurThread -- how many times we went to do a hedged read but we had to run it in the current thread because dfs.client.hedged.read.threadpool.size was at a maximum.</blockquote></li>
