Question: I started learning C++ using a ebook and got interupted by a few lines, which I think are a bit outdated. Anyway, what I am trying to do is using a preprocessor directive as a function parameter which isnt working:

```
#define TitleLabelId 1000;

//....

hTitleText = CreateWindow(L"STATIC",
                          L"Test Text",
                          WS_VISIBLE | WS_CHILD,
                          0, 0,
                          300, 20,
                          hWnd,
                          (HMENU)TitleLabelId,
                          hInst,
                          NULL);

```

This gives me an compile error, while this will give me a correct result:

```
HMENU hm = (HMENU)TitleLabelId;

hTitleText = CreateWindow(L"STATIC",
                          L"Test Text",
                          WS_VISIBLE | WS_CHILD,
                          0, 0,
                          300, 20,
                          hWnd,
                          (HMENU)TitleLabelId,
                          hInst,
                          NULL);

```

I tried to outsource the Label Text aswell but unfortunateley it didnt work either using the following directive:

```
#define TitleText L"Blob Color War";

```

Is it anything with the syntax I have overseen? Thanks in advance!

The answer is located in <http://www.cloudera.com/content/cloudera-content/cloudera-docs/CDH5/5.0/CDH5-Installation-Guide/cdh5ig_hive_schema_tool.html>

To suppress the schema check and allow the metastore to implicitly modify the schema, you need to set the hive.metastore.schema.verification configuration property to false in hive-site.xml.
I was facing the same issue there are some important point's that could be resolve this problem.

**1.Put the following at the beginning of hive-site.xml**

```
  <property>
    <name>system:java.io.tmpdir</name>
    <value>/tmp/hive/java</value>
  </property>
  <property>
    <name>system:user.name</name>
    <value>${user.name}</value>
  </property>
  <property>
    <name>javax.jdo.option.ConnectionURL</name>
    <value>jdbc:derby:,databaseName=$HIVE_HOME/metastore_db;create=true</value>
    <description>JDBC connect string for a JDBC metastore </description>
  </property>

```

this is set relative path in absolute URI and configuring Metastore where the database is stored

**2.Remove `$HIVE_HOME/metastore_db` But Be aware, this will remove your schema completely!**

**3.Now,You must Initialize Derby database.By default, Hive uses Derby database**

> 
> $HIVE\_HOME/bin/schematool -initSchema -dbType derby

also I suppose that your environment variable has been set correctly ,if not please check them that are looking like below:

```
export HADOOP_HOME=/usr/local/hadoop 
export PATH=$PATH:$HADOOP_HOME/bin
export PATH=$PATH:$HADOOP_HOME/sbin
export HIVE_HOME=/usr/lib/hive
export PATH=$PATH:$HIVE_HOME/bin

```

and then run `hive` command and type `show databases;`
