I have also checked that spark behaves the same way when it is talking
directly to HDFS HA:
val s = sc.textFile("hdfs://stanley/tmp/proxy.txt")
s.count()
(first time error) UnknownHostException
(important to assign once again the variable)
val s = sc.textFile("hdfs://stanley/tmp/proxy.txt")
s.count()
res: 5
I guess tachyon is not the guilty one here,
Any help appreciated
