-------------------------------------
Summary: CredentialProviderFactory fails at class loading from
libhdfs (JNI)
Key: HADOOP-13476
URL: https://issues.apache.org/jira/browse/HADOOP-13476
Project: Hadoop Common
Issue Type: Bug
Components: fs/s3
Affects Versions: 2.8.0, 2.9.0, 3.0.0-alpha2
Reporter: Aaron Fabbri
Assignee: Aaron Fabbri
This bug was discovered when trying to run Impala (libhdfs.so) with s3a and
Java KeyStore credentials. Because JNI threads have a different classloader
(bootstrap), we fail to load JavaKeyStoreProvider.
