------------------------------------
Summary: Setting ACCUMULO_CLIENT_CONF_PATH with no client.conf
file present throws ConfigurationException
Key: ACCUMULO-4026
URL: https://issues.apache.org/jira/browse/ACCUMULO-4026
Project: Accumulo
Issue Type: Bug
Components: client, core
Affects Versions: 1.7.0
Reporter: Jim Klucar
Priority: Trivial
Setting the environment variable ACCUMULO_CLIENT_CONF_PATH to a directory that
exists but does not contain a file named client.conf throws
org.apache.commons.configuration.ConfigurationException: Cannot load a
configuration from a directory
To demo this, simply set ACCUMULO_CLIENT_CONF_PATH to /tmp, make sure
client.conf doesn't exist in /tmp and try to run the accumulo shell.
The problem is ClientConfiguration.java on line 221 checks File.canRead() which
is true for a Directory and a File. The solution is to make the branch check
File.isFile() && File.canRead()
