--------------------------------
Summary: [SECURITY]newCachedThreadPool() has higher risk in
causing OutOfMemoryError
Key: MAHOUT-2065
URL: https://issues.apache.org/jira/browse/MAHOUT-2065
Project: Mahout
Issue Type: Bug
Reporter: bd2019us
Location :
community/mahout-mr/mr/src/main/java/org/apache/mahout/clustering/streaming/mapreduce/StreamingKMeansDriver.java:427
Executors.newCachedThreadPool() is not secure when the number of threads is not
bounded, which can cause OutOfMemoryError and crash the program. For security,
using newFixedThreadPool(int) should be preferred, which can be freely
configured manually on demand.
