Two node cluster

[B H]

Hi,

I tried to run a two node cluster. When I run the client via terminal, it connected successfully. But when I tried to put a key value pair e.g. put "hello" "world", it prompts a ClassCastException: String cannot be cast to [B

Anyone encounter this error? Is there a way to fix this?

This is a character encoding issue...

Byte arrays are not straightforward to type in the shell.

It may be easier to configure your Store Definition to use strings for its schema.

How can I configure the Store Definition? Which file it resides in ?

In the config directory, there should be a STORES directory, containing one xml file per store.

The structure of my config directory is as such

node_0 > config > STORES > test

Are you talking about the test file? The test file looks like this.

<store>
<name>test</name>
<persistence>bdb</persistence>
<description>Test store</description>
<owners>******@hogwarts.edu, ******@hogwarts.edu</owners>
<routing-strategy>consistent-routing</routing-strategy>
<routing>server</routing>
<replication-factor>2</replication-factor>
<preferred-reads>2</preferred-reads>
<required-reads>1</required-reads>
<required-writes>1</required-writes>
<key-serializer> <type>identity</type> </key-serializer>
<value-serializer> <type>java-serialization</type> </value-serializer>
<hinted-handoff-strategy>consistent-handoff</hinted-handoff-strategy>
</store>

Yes, that's what I'm talking about. For the purpose of testing with the shell, you could try setting the store's key and value serializer type to string.
