Answer 1

Check your core-site.xml :

<property>
    <name>fs.default.name</name>
    <value>hdfs://host:port</value>
</property>

This port can be 9000 or 8020. Make sure that you are using the same port in your code or command

Answer 2

try this solution: add this config to hdfs-site.xml

<property>
     <name>ipc.maximum.data.length</name>
     <value>134217728</value>
</property>
