### What problem does this PR solve?
Problem Summary:
In HiveMetaStoreCache, the function FileInputFormat.setInputPaths is
used to set input paths. However, this function splits paths using
commas, which is not the expected behavior. As a result, when partition
values contain commas, it leads to incorrect path parsing and potential
errors.
```java
public static void setInputPaths(JobConf conf, String org.apache.hadoop.shaded.com.aSeparatedPaths) {
setInputPaths(conf, StringUtils.stringToPath(
getPathStrings(org.apache.hadoop.shaded.com.aSeparatedPaths)));
}
```
To prevent FileInputFormat.setInputPaths from splitting paths by commas,
we use another overloaded version of the method. Instead of passing a
comma-separated string, we explicitly pass a Path object, ensuring that
partition values containing commas are handled correctly.
```java
public static void setInputPaths(JobConf conf, Path... inputPaths) {
Path path = new Path(conf.getWorkingDirectory(), inputPaths[0]);
StringBuffer str = new StringBuffer(StringUtils.escapeString(path.toString()));
for(int i = 1; i < inputPaths.length;i++) {
str.append(StringUtils.COMMA_STR);
path = new Path(conf.getWorkingDirectory(), inputPaths[i]);
str.append(StringUtils.escapeString(path.toString()));
}
conf.set(org.apache.hadoop.shaded.org.apache.hadoop.mapreduce.lib.input.
FileInputFormat.INPUT_DIR, str.toString());
}
```
