Sergey Soldatov created HBASE-26767: ---------------------------------------
Summary: Rest server should not use a large Header Cache. Key: HBASE-26767 URL: https://issues.apache.org/jira/browse/HBASE-26767 Project: HBase Issue Type: Bug Components: REST Affects Versions: 2.4.9 Reporter: Sergey Soldatov Assignee: Sergey Soldatov In the RESTServer we set the HeaderCache size to DEFAULT_HTTP_MAX_HEADER_SIZE (65536). That's not compatible with jetty-9.4.x because the cache size is limited by Character.MAX_VALUE - 1 (65534) there. According to the Jetty source code comments, it's possible to have a buffer overflow in the cache for higher values and that might lead to wrong/incomplete values returned by cache and following incorrect header handling. There are a couple of ways to fix it: 1. change the value of DEFAULT_HTTP_MAX_HEADER_SIZE to 65534 2. make header cache size configurable and set its size separately from the header size. I believe that the second would give us more flexibility. -- This message was sent by Atlassian Jira (v8.20.1#820001)
