ECFuzz updated HDFS-17238:
--------------------------
Description:
My hadoop version is 3.3.6, and I use the Pseudo-Distributed Operation.
core-site.xml like below.
{code:java}
<configuration>
<property>
<name>fs.defaultFS</name>
<value>hdfs://localhost:9000</value>
</property>
<property>
<name>hadoop.tmp.dir</name>
<value>/home/hadoop/Mutil_Component/tmp</value>
</property>
</configuration>{code}
hdfs-site.xml like below.
{code:java}
<configuration>
<property>
<name>dfs.replication</name>
<value>1</value>
</property>
<property>
<name>dfs.blocksize</name>
<value>1342177280000</value>
</property>
</configuration>{code}
And then format the namenode, and start the hdfs. HDFS is running normally.
{code:java}
hadoop@hadoop-Standard-PC-i440FX-PIIX-1996:~/Mutil_Component/hadoop-3.3.6$
bin/hdfs namenode -format
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx(many info)

Starting namenodes on [localhost]
Starting datanodes
Starting secondary namenodes [hadoop-Standard-PC-i440FX-PIIX-1996] {code}
Finally, use dfs to place a file.
{code:java}
bin/hdfs dfs -mkdir -p /user/hadoop
bin/hdfs dfs -mkdir input
bin/hdfs dfs -put etc/hadoop/*.xml input {code}
Discovering Exception Throwing.
