Which mode of hadoop and HDFS needed to be instlled? - hadoop

Question

I am a beginner to hadoop and HDFS, Now I have a situation where I need to connect 3 different PC having a file, NIFI and Hadop+HDFS.
Machine 1 : Will have a .csv file
Machine 2(Personal laptop): Will have my NIFI running to it.
Machine 3(Running at my office) : will have Hadoop+HDFS in it.
Now I would like to send a csv file from machine 1 to my database running on machine 3 using nifi which is running on machine 2.
I connect to machine 3 using ssh connection which is basically a router at my office.
Question:How can I connect to machine 3 from machine 2 which has nifi which can send the file to my hadoop hbase.
Should I use public key as configuration or should I use a different setup or server?
My configuration of files of haddo and hdfs are as follows
hbase-site.xml
<configuration>
<property>
<name>hbase.cluster.distributed</name>
<value>true</value>
</property>
<property>
<name>hbase.rootdir</name>
<value>hdfs://localhost:9000/hbase</value>
</property>
<property>
<name>hbase.zookeeper.property.clientPort</name>
<value>2222</value>
</property>
<property>
<name>hbase.zookeeper.property.dataDir</name>
<value>/home/hadoop/zookeeper</value>
</property>
</configuration>
<property>
<name>hbase.wal.provider</name>
<value>filesystem</value>
</property>
<property>
<name>hbase.tmp.dir</name>
<value>./tmp</value>
</property>
</configuration>
core-site.xml
<configuration>
<property>
<name>hadoop.tmp.dir</name>
<value>/home/hdoop/tmpdata</value>
</property>
<property>
<name>fs.default.name</name>
<value>hdfs://localhost:9000</value>
</property>
</configuration>
hdfs-site.xml
<configuration>
<property>
<name>dfs.replication</name>
<value>1</value>
</property>
<property>
<name>dfs.name.dir</name>
<value>file:///home/hadoop/hdfs/namenode</value>
</property>
<property>
<name>dfs.data.dir</name>
<value>file:///home/hadoop/hdfs/datanode</value>
</property>
</configuration>
Look in to the configuration files and let me know where I need to change the properties and also I have install til now the psudo distributed mode HDFS in machine 3.

Answer 1

Pseudo distributed and fully distributed aren't any different.
You say only machine 3 has HDFS. Therefore only it needs to be running a Namenode and Datanode, setup in a distributed fashion, meaning that external clients will be able to communicate with it.
More specifically, no config file should be using localhost and should instead use LAN IP or hostnames
