All parameters are optional and should only be set if the defaults need to be overridden. Authentication should be automatic if the HDFS cluster uses Kerberos. However, if a username is specified, then the ticket cache will likely be required. .. deprecated:: 2.0 ``pyarrow.hdfs.connect`` is deprecated, please use ``pyarrow.fs.HadoopFileSystem`` instead. Parameters ---------- host : NameNode. Set to "default" for fs.defaultFS from core-site.xml. port : NameNode's port. Set to 0 for default or logical (HA) nodes. user : Username when connecting to HDFS; None implies login user. kerb_ticket : Path to Kerberos ticket cache. extra_conf : dict, default None extra Key/Value pairs for config; Will override any hdfs-site.xml properties Notes ----- The first time you call this method, it will take longer than usual due to JNI spin-up time.
