1. Inject Map using Value annotation and SpEL
values in application.properties:
  value1=1000
  value2=2000
code:  
  @Value("#{{KEY1: ${value1}, KEY2: ${value2}}}")
  private Map<String, Integer> map = new HashMap<>();

1. After running changeset changelog's file name is stored in table databasechangelog column filename.
During liquibase next run several filters check eligibilty for every changeset, one of them is ShouldRunChangeSetFilter
which checks: 
            idsAreEqual(changeSet, ranChangeSet)
         && authorsAreEqual(changeSet, ranChangeSet)
         && pathsAreEqual(changeSet, ranChangeSet)
so if path is different but content the same liquibase tries to run changeset anyway. 
There is attribute to "hardcode" path and after that no matter what is the path to file. 
Attribute is
        logicalFilePath="upgrade/db-changelog.xml"

An index for a MySQL CLOB column cannot be created with Liquibase createIndex at the moment, 
since MySQL requires a length limit for this index, see http://dev.mysql.com/doc/refman/5.5/en/create-index.html

As a workaround, you can use the modifySql to 'fix' the sql generated like so:
<createIndex tableName="foo" indexName="i_foo">
    <column name="myClobColumn"/>
</createIndex>
<modifySql dbms="mysql">
    <replace replace="myClobColumn" with="myClobColumn(80)"/>
</modifySql>
