----------------------------------
Summary: DataNodeHttpServer hard-codes HttpServer2 threads at 10
Key: HDFS-13272
URL: https://issues.apache.org/jira/browse/HDFS-13272
Project: Hadoop HDFS
Issue Type: Bug
Components: datanode
Reporter: Erik Krogen
Assignee: Erik Krogen
In HDFS-7279, the Jetty server on the DataNode was hard-coded to use 10
threads. In addition to the possibility of this being too few threads, it is
much higher than necessary in resource constrained environments such as
MiniDFSCluster. To avoid compatibility issues, rather than using
{{HttpServer2#HTTP_MAX_THREADS}} directly, we can introduce a new configuration
for the DataNode's thread pool size.
