Improved the script from https://jpetazzo.github.io/2015/01/13/docker-mount-dynamic-volumes/ to work with more scenarios. Save this file in the same directory as nsenter (https://github.com/jpetazzo/nsenter) and chmod +x it. This allows you to mount a host path on a running container. You may have to adjust the ownership of the mounted directory…
#!/bin/bash -e
# Based on https://jpetazzo.github.io/2015/01/13/docker-mount-dynamic-volumes/
SCRIPT_DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"
[[ $# -eq 3 ]] || {
echo "Usage: $0 <container_name_or_id> <host_path> <container_path>" 1>&2
exit 1
}

Cause of "Failed to renew token: Kind: HDFS_DELEGATION_TOKEN"

One of the reasons that this failure occurs is because of the incorrect client setting of yarn.resourcemanager.cluster-id that ends up not matching the one in the cluster. This often results in a cryptic error that looks like this:

Failed to renew token: Kind: HDFS_DELEGATION_TOKEN, Service: ha-hdfs:test-local-EMPTY, Ident: (HDFS_DELEGATION_TOKEN token 40242 for hari)

Unfortunately, the original IOException seems to get completely lost, neither logged on the server nor gets seen on the client. When I put an extra trace log line to print the exception, I got this:

2016-06-06 12:57:57,394 ERROR [tionTokenRenewer #50] security.DelegationTokenRenewer - Failed to renew token: Kind: HDFS_DELEGATION_TOKEN, Service: ha-hdfs:test-local-EMPTY, Ident: (HDFS_DELEGATION_TOKEN token 40663 for sfdc)
java.io.IOException: Unable to map logical nameservice URI 'hdfs://test-local-EMPTY' to a NameNode. Local configuration does not have a failover proxy provider configured.
