1. 制作cassandra and ycsb

1.1 編譯安裝netcat

$ wget http://sourceforge.net/projects/netcat/files/netcat/0.5.0/netcat-0.5.0.tar.gz
$ tar -zxvf netcat-0.5.0.tar.gz
$ cd netcat-0.5.0
$ ./configure --prefix=/opt/netcat --build=arm
$ make -j
$ make install
$ nc --help

?1.2 cassandra錯誤排除

?1.2.1 日志/var/log/cassandra/cassandra.log報：

The stack size specified is too small, Specify at least 228k
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

解決：修改/etc/cassandra/cassandra-env.sh中JVM_OPTS="$JVM_OPTS -Xss512k"

1.3 搜集虛擬機信息出現錯誤

SysV configuration data might be overridden by nativesystemd configuration.If you want to list systemd services use 'systemctl list-unit-files'.To see services enabled on particular target use'systemctl list-dependencies [target]'.

需要安裝brctl和dpkg，具體如下：

sudo yum install bridge-utils
sudo yum install dpkg

2. cbtool工具bug

2.1 連接到云后，當使用aiattach cassandra_ycsb時，容易出現：

無法發現flavors問題

解決方式：通過修改osk_cloud_ops.py
