Unable to start hive metastore service or hive-she

Question

I know this question asked already but those answers are not helping in any way.

I am spending more time to configure mysql with hive, Every time I encounter errors and I don't understand where it goes wrong ..... as you can see in this link,

hive-site.xml configuration can be seen here in the link

Here is file-structure

So is the reason creating this question.... Hoping this helps me to resolve.

I followed these links

    <value></value>
    <description>If true (default is false), ALTER TABLE operations which change the type of   a column (say STRING) to an incompatible type (say MAP&lt;STRING, STRING&gt;) are disallowed.    RCFile default SerDe (ColumnarSerDe) serializes the values in such a way that the  datatypes can be converted from string to any type. The map is also serialized as  a string, which can be read as a string as well. However, with any binary   serialization, this is not true. Blocking the ALTER TABLE prevents ClassCastExceptions  when subsequently trying to access old partitions.   Primitive types like INT, STRING, BIGINT, etc are compatible with each other and are   not blocked.
