all nodes fail to start up - hadoop

Question

I set up my configuration files and formatted my file system already but whenever I try to execute the start shell scripts I get this error.
Below I put the alias for hstart
Error:

jps also says that none of the nodes are up after running the start scripts. From what I have researched it seems like it may be something wrong with my hostnames however trying to change those hasn't fixed anything.
I will provide my other config files to show how they are setup for context.
/usr/local/hadoop/etc/hadoop/core-site.xml
<configuration>
<property>
<name>hadoop.tmp.dir</name>
<value>/app/hadoop/tmp</value>
<description>A base for other temporary directories.</description>
</property>
<property>
<name>fs.default.name</name>
<value>hdfs://localhost:9000</value>
<description>The name of the default file system. A URI whose scheme and
authority determine the FileSystem implementation. The uri's scheme determines
the config property (fs.SCHEME.impl) naming the FileSystem implementation
class. The uri's authority is used to determine the host, port, etc. for a filesystem.

/usr/local/hadoop/etc/hadoop/hdfs-site.xml
<configuration>
<property>
<name>dfs.replication</name>
<value>1</value>
<description>Default block replication.
The actual number of replications can be specified when the file is created.
The default is used if replication is not specified in create time.

</configuration>
I made a few changes to my hadoop-env.sh as well. I will put those below.
/usr/local/hadoop/etc/hadoop/hadoop-env.sh
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home
and
export HADOOP_OPTS="$HADOOP_OPTS -Djava.net.preferIPv4Stack=true -Djava.security.krb5.realm= -Djava.security.krb5.kdc="
.bashrc
#Hadoop variables
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home
export HADOOP_INSTALL=/usr/local/hadoop
export PATH=$PATH:$HADOOP_INSTALL/bin
export PATH=$PATH:$HADOOP_INSTALL/sbin
export HADOOP_MAPRED_HOME=$HADOOP_INSTALL
export HADOOP_COMMON_HOME=$HADOOP_INSTALL
export HADOOP_HDFS_HOME=$HADOOP_INSTALL
export YARN_HOME=$HADOOP_INSTALL
export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_INSTALL/lib/native
export HADOOP_OPTS="-Djava.library.path=$HADOOP_INSTALL/lib/native"
###end of paste
.bash_profile
alias hstart="/usr/local/hadoop/sbin/start-dfs.sh;/usr/local/hadoop/sbin/start-yarn.sh"
alias hstop="/usr/local/hadoop/sbin/stop-yarn.sh;/usr/local/hadoop/sbin/stop-dfs.sh"
I'm not sure what the next step to take from here is having looked at pretty much every file involved.

Answer 1

I think you have spaces in your Mac's hostname. For example, Seans Mac
The default log files are named using that,
HDFS: log=$HADOOP_LOG_DIR/hadoop-$HADOOP_IDENT_STRING-$command-$HOSTNAME.out
YARN: log=$YARN_LOG_DIR/yarn-$YARN_IDENT_STRING-$command-$HOSTNAME.out
Where $HOSTNAME is the issue, and spaces are unexpected.
If you look at the output, you'll notice hadoop-seanplowman-namenode-Seans, so I suspect
HADOOP_IDENT_STRING = user running the scripts = seanplowman
command = hadoop
HOSTNAME = Seans Mac
See if fixing the hostname without spaces changes anything.
If not, edit the yarn-daemon.sh and hadoop-daemon.sh scripts to start with
#!/usr/bin/env bash
set -xv
Then edit the question with the outputs
