JIRA – https://issues.apache.org/jira/browse/HADOOP-19672
In case of a network error while using the Apache client, we allow the
client to switch over from Apache to JDK. This network fallback occurs in two
scenarios:
1. During file system initialization – When warming up the cache, if no
connection is created (indicating an issue with the Apache client), the system
will fall back to the JDK.
2. During a network call – If an I/O or Unknown Host exception occurs for
three consecutive retries, the system will fall back to the JDK.
This fallback is applied at the JVM level, so all file system calls will use
the JDK client once the switch occurs.
There is also a possibility of recovery. During cache warmup, if connections
are successfully created using the Apache client, the system will automatically
switch back to the Apache client.
