Kerberos support on hdfs3 0.1.4, libgsasl 1.8.0

[KimiRaikking]

I have conda installed hdfs3=0.1.4 which depends on libgsasl=1.8.0, I checked libgsasl.so , execute ldd libgsasl.so, I think it support GSSAPI , but i can not connect to hdfs which has kerberos auth.
My code is like this:

import hdfs3
from hdfs3 import HDFileSystem
import subprocess
result = subprocess.getoutput('source /opt/client/bigdata_env; kinit -kt /opt/client/AIFlow.keytab AIFlow;klist')
ticket_path = "/tmp/krb5cc_1002"

print(result)
conf = {
    "hadoop.security.authentication" : "kerberos",
    "dfs.nameservices" : "hacluster,haclusterX,haclusterX1,haclusterX2,haclusterX3,haclusterX4",
    "dfs.ha.namenodes.hacluster" : "96,97",
    "dfs.namenode.rpc-address.hacluster.96" : "szvphicpra49709:25000",
    "dfs.namenode.rpc-address.hacluster.97" : "szvphicpra49710:25000"
}
hdfs1 = HDFileSystem(host="szvphicpra49709", port=25000 , pars = conf , user = "AIFlow", ticket_cache = ticket_path)

my libgsasl.so

I advise you to try with arrow's hdfs interface.

yes, i prefer to use pyarrow, and it works with kerberos.
