Erik Krogen created HDFS-14462: ---------------------------------- Summary: WebHDFS throws "Error writing request body to server" instead of NSQuotaExceededException Key: HDFS-14462 URL: https://issues.apache.org/jira/browse/HDFS-14462 Project: Hadoop HDFS Issue Type: Bug Components: webhdfs Affects Versions: 3.1.2, 2.7.7, 2.8.5, 3.0.3, 2.9.2, 3.2.0 Reporter: Erik Krogen
We noticed recently in our environment that, when writing data to HDFS via WebHDFS, a quota exception is returned to the client as: {code} java.io.IOException: Error writing request body to server at sun.net.www.protocol.http.HttpURLConnection$StreamingOutputStream.checkError(HttpURLConnection.java:3536) ~[?:1.8.0_172] at sun.net.www.protocol.http.HttpURLConnection$StreamingOutputStream.write(HttpURLConnection.java:3519) ~[?:1.8.0_172] at java.io.BufferedOutputStream.flushBuffer(BufferedOutputStream.java:82) ~[?:1.8.0_172] at java.io.BufferedOutputStream.flush(BufferedOutputStream.java:140) ~[?:1.8.0_172] at java.io.FilterOutputStream.flush(FilterOutputStream.java:140) ~[?:1.8.0_172] at java.io.DataOutputStream.flush(DataOutputStream.java:123) ~[?:1.8.0_172] {code} It is entirely opaque to the user that this exception was caused because they exceeded their quota. Yet in the DataNode logs: {code} 2019-04-24 02:13:09,639 WARN org.apache.hadoop.hdfs.DFSClient: DataStreamer Exception org.apache.hadoop.hdfs.protocol.DSQuotaExceededException: The DiskSpace quota of /foo/path/here is exceeded: quota = XXXXXXXXXXXX B = X TB but diskspace consumed = XXXXXXXXXXXXXXXX B = X TB at org.apache.hadoop.hdfs.server.namenode.DirectoryWithQuotaFeature.verifyStoragespaceQuota(DirectoryWithQuotaFeature.java:211) at org.apache.hadoop.hdfs.server.namenode.DirectoryWithQuotaFeature.verifyQuota(DirectoryWithQuotaFeature.java:239) {code} This was on a 2.7.x cluster, but I verified that the same logic exists on trunk. I believe we need to fix some of the logic within the {{ExceptionHandler}} to add special handling for the quota exception. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
