Akira AJISAKA commented on HDFS-6565: ------------------------------------- Attaching a patch to remove jetty json library from JsonUtil and WebHdfsFileSystem. The way Jackson parse JSON number is different from jetty json: * Jackson: number -> Integer, Long, or BigInteger (smallest applicable) * jetty json: number -> Long so I changed the code for parsing JSON number {code} (Long) m.get("blockId") // doesn't work if m.get("blockId") is Integer {code} to {code} ((Number) m.get("blockId")).longValue() // support all classes extends Number {code} In addition, the way Jackson parse JSON array is different from jetty json: * Jackson: array -> ArrayList<Object> * jetty json: array -> Object[] so I changed the code for parsing JSON array {code} (Object[]) m.get("locatedBlocks") {code} to {code} (List<Object>) m.get("locatedBlocks") {code} > Use jackson instead jetty json in hdfs-client > --------------------------------------------- > > Key: HDFS-6565 > URL: https://issues.apache.org/jira/browse/HDFS-6565 > Project: Hadoop HDFS > Issue Type: Bug > Reporter: Haohui Mai > Assignee: Akira AJISAKA > Attachments: HDFS-6565.patch > > > hdfs-client should use Jackson instead of jetty to parse JSON. -- This message was sent by Atlassian JIRA (v6.2#6252)
